QNAP RAM-16GDR4A1-UD-2400 16GB DDR4 UDIMM Memory Module
Overview
The RAM-16GDR4A1-UD-2400 is a 16GB DDR4 unbuffered DIMM (UDIMM) running at 2400 MHz, supplied by QNAP for use in compatible QNAP NAS enclosures and server appliances. Upgrading RAM in a QNAP system with a qualified module like the RAM-16GDR4A1-UD-2400 matters in workloads where the NAS is handling simultaneous virtualization, heavy concurrent user access, or surveillance recording with real-time transcoding — more headroom means fewer bottlenecks at the application layer rather than the storage layer.
Compatibility
This module is designed for QNAP NAS systems that accept DDR4-2400 UDIMM memory. Compatible enclosures typically include select models from the QNAP TVS and TS series NAS lines that specify DDR4 UDIMM slots. Always verify your specific enclosure's NAS memory specification against the RAM-16GDR4A1-UD-2400 before purchasing — QNAP publishes a compatibility list per chassis model on their support site. Using a non-qualified module can result in system instability or the NAS refusing to POST. This module is not intended for ECC-only or RDIMM-only systems.
Installation Notes
Power down the NAS and disconnect all cables before handling memory. DDR4 UDIMMs are keyed — align the notch to the slot before seating. Apply firm, even pressure until both retention clips engage. If expanding beyond a single DIMM slot, consult the chassis documentation for preferred slot population order, as some QNAP models require specific slot sequencing for dual-channel operation. After installation, verify the module is recognized in the QNAP QTS or QuTS hero system resource monitor before returning the system to service.
